일반 설명

trans-1-methoxy-3-trimethylsiloxy-1,3-butadiene is a funtionalized Diels-Alder diene. Mukaiyama-Michael-type addition/heterocyclization of trans-1-methoxy-3-trimethylsiloxy-1,3-butadiene (Danishefsky′s diene) with 1,2-diaza-1,3-butadiene has been investigated. Asymmetric hetero-Diels-Alder cyclization of Danishefsky′s diene with benzaldehyde catalyzed by mesoporous inorganic/metalorganic hybrid materials has been reported.

애플리케이션

trans-1-Methoxy-3-trimethylsiloxy-1,3-butadiene was used:
  • in the synthesis of sulfone analogues of griseofulvin (sulfogriseofulvins), 4H-1-aminopyrroles and 4,5H-pyrazoles
  • as Diels-Alder diene for the synthesis of pyridones and pyranones
  • as reagent employed in the Mannich-Michael reaction for preparation of piperidinones and enaminones

Syntheses of substituted, especially of fluoro substituted benzoxathiole 1,1-dioxides, are described. These derivatives were transformed via the Peterson olefination into substituted 2-alkylidene derivatives 27. Diels-Alder reactions of 27 with 1,1-dimethoxy- and 1-methoxy-3-trimethylsiloxy-1,3-butadiene (30, 32) gave sulfone analogues 31 of griseofulvin

The paper describes the course of cycloadditions of Diels-Alder dienophiles containing linked enyne sites, each substituted with activating groups. Consistently, it was found that in the enyne cases the Diels-Alder reaction occurred specifically at the acetylenic center. Furthermore, it was

The versatility of the Mukaiyama-Michael-type addition/heterocyclization of Danishefsky's diene with 1,2-diaza-1,3-butadienes was applied to the synthesis of both 4 H-1-aminopyrroles and 4,5 H-pyrazoles. Thus, the same reagents furnished different types of highly functionalized azaheterocycles essentially depending on their structure: as
